Snake_bb, I think your son's behavior is normal. My gal was also very clingy, more on the shy side. I used to park her at my PIL's place when I worked. That time she was 1plus till 3 plus. She became so close to them that I barely retained my no.1 position in her life. Her daddy was at no. 4 spot. I did feel jealous, but I also knew my PIL loved and cared well for her a lot. Perhaps what helped was that we had consistent routine at home, and years later I realized I was the one who gave her the most hugs and kisses. Also society, especially school, will always mention daddy and mummy, never maid. Friends and family will always ask her about the parents. So impression in her mind is always about daddy, mummy.
I also sent her to N1 at 24 months cos she's a Dec baby. Teacher usually had to carry her into classroom. No matter enrichment or school, unless I was there, then she wouldnt cry. Finally when she turned four, she cried first few days of school, then stopped crying. Now she's five, can shoo the parents away (?!?) after stepping into classroom.
Perhaps what u can do is take over helping your boy into his pajamas, then read a short story/sing songs etc. 10-15min daily is also good bonding time. When you're feeling better, can do more, but must always have consistent routine. This way your son will look forward to his time with you. At this time, I would only really about your maid if she starts playing power games with you over your son, or she abuses him.
And the 7th month bb thing? Not true la. My friend's kid was born in Jan, all along has weak stomach. Cry too much, vomit. Cough too much when sick, vomit. Used to take 20-30min to drink 150ml milk. Each kid will come up with his/her own issues. Cannot get perfect one la. If got I also want.
Btw, I still in no.1 position
. Hubby has shifted to no. 2 haha!
