first, can't be that bad.
i go often to baby groups in my area, mostly for breast feeding support, and they are great, even if it is just to have someone hold your baby for half an hour while you have a glass of squash and biscuits, no cups of tea around children, i'm afraid... they also tell you all the anecdotes of their first few weeks, and it's a great excuse to leave the house, believe me, no matter how tired you are, all looks a lot worst after a couple of days at home.
on a positive note, oscar has been weight today at 12 weeks and he has reach 13 lb, 50th centile, from 9th, not bad, he is also 61 cm long, nearly 75th centile, not quite, from 9th as well, very well please with myself, found new confidence and lost all guilt for my mixed feeding, hvs well impressed with the growth, can also lift himself from the ground if i hold his hands, only top half, the 3 hvs spendt half an hour playing with him. must be doing something right...
